Auto Parts: help with headers please, turbo mufflers, length headers

Question
Hello,

I own a 1980 camaro with a 350 and 4 speed manual. Ive put a voodoo cam, new carb, and alumimun intake on it, but everything else is pretty much stock.  I'd like to get a set of headers and put on new dual exhaust.  The problem is that there are about a trillion different options for ordering headers and I cant make up my mind on what to get.  Ive heard nothing but horror stories when people order full length headers because they end up having to modify and adjust the heck out of their car to make them fit or have ground clearance issues.  Ideally, Id really like to just order some shorty headers and spend somewhere around 125 bucks.  I came across these (link is below).  What do you think of these headers?  Do you believe they'd work well? Honestly, I feel lost and any advice would be greatly appreciated.  I just dont want to drop 500 dollars and have to cut into my A-arm just to have headers.

Also, any suggestions on mufflers?  I want my car to be loud, but I am getting a little too old for the sound of glass packs. Flowmaster sounds great but its so expensive...any suggestions for a similar sound, but less price?

I would REALLY appreciate any and all advice!

Answer
    The problem with shorty headers is that you then have to buy your exhaust from the same guys so that it will fit the headers.  If you buy full length headers you can fab up an exhaust from anybody.  My recommendation would be a set of full-length headers from Dynomax combined with one of Dynomax's inexpensive header-back kits made specifically for the Camaro.  They are the cheapest thing you will find, and they will fit well because they've had thirty years to get the bugs out of any fitment issues (use the cheap Dynomax turbo mufflers, they work good and never give any trouble).  Adapter brackets may be required for the A/C compressor and alternator, but they are cheap as well.  If you've any doubts, call them and ask.  And don't let them sell you up to higher priced stuff, you don't need it.
    
    I would also (you said everything else was stock) upgrade the ignition system, it's the most important part of the engine.
